Joomla IDoBlog Component "userid" SQL Injection

SECUNIA ADVISORY ID:
SA36243

VERIFY ADVISORY:
http://secunia.com/advisories/36243/

DESCRIPTION:
KKR has discovered a vulnerability in the IDoBlog component for
Joomla, which can be exploited by malicious people to conduct SQL
injection attacks.

Input passed to the "userid" parameter in the Joomla! installation's
index.php script (when "option" is set to "com_idoblog" and "task" to
"profile") is not properly sanitised before being used in SQL queries.
This can be exploited to manipulate SQL queries by injecting arbitrary
SQL code.

The vulnerability is confirmed in version 1.1. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
